概括
基于探头的共聚焦激光内微镜 (pCLE) 可以通过评估粘膜的愈合来预测性结肠炎复发. 肠道屏障完整且没有炎症的患者没有复发,表明pCLE.
科学领域:
- 胃肠病学 胃肠病学
- 炎症性肠道疾病研究研究
- 医学成像和诊断 医学成像和诊断
背景情况:
- 目前的性结肠炎 (UC) 管理目标是内镜治疗,但显微的炎症和屏障功能障碍增加了复发风险.
- 识别患有复发高风险的患者对于优化UC治疗策略至关重要.
研究的目的:
- 评估基于探针的共聚焦激光内显微镜 (pCLE) 是否可以识别结构和功能性粘膜异常,预测UC治疗点的损失.
- 评估PCLE在预测UC患者临床和内镜复发中的预后价值.
主要方法:
- 对81名UC患者进行了24个月的临床和内镜缓解的前性单中心研究.
- 基线评估包括用PCLE进行结肠镜检查和检查组织学炎症 (HI) 和大肠和大肠中的屏障功能障碍的活检.
- 每3个月进行一次临床评估.
主要成果:
- 改变的结肠透性 (OR=3.85) 和PCLE检测到的HI (OR=6.04) 预测了内镜缓解的丧失.
- 改变的阴道 (HR=6.01) 或结肠 (HR=6.51) 屏障功能增加了临床复发风险.
- 在基线时的三重愈合 (组织愈合,完整的乳腺和结肠透性) 预测没有复发.
结论:
- 与标准评估相比,pCLE在预测UC复发方面提供了更好的预后价值.
- 通过PCLE进行形态和功能评估可以作为预防UC复发的治疗目标.
- 实现三重愈合与UC患者的持续缓解有关.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
998
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
